- Abstract
- In this study, PI fiber and nonwoven fabric were fabricated for the manufactureof PI fiber high-temperature filter. The PI fiber was made in two steps, and poly(amin acid)(PAA) was polymerized by polymerizing 4,4’-oxydianiline (ODA) as an aromatic aminebasedmonomer and pyromellitic dianhydride (PMDA) as a solvent with N,N-dimethylacetamide(DMAc). PAA fibers were manufactured by wet spinning, PI fibers were manufacturedby imidizing PAA fibers, and the properties of non-woven fabrics were investigated. To confirm the degree of imidization, various tests such as FT-IR analysis and shrinkage,heat resistance, deterioration analysis, maximum operating temperature, chemical resistance,and dust collection efficiency were also performed.
